Considering a hitch weight equalizer

To minimize the towing vehicle bouncing on uneven roads, I am planning to install a trailer hitch weight equalizer/sway bar on a 2017 179 RPod. Does anyone have any suggestions on brand, type or weight specifications? Is there any advantage/disadvantage to using the type with chains at the end of the longest bars? I pull the pod with a 2005 Tacoma V-6 Access cab.
Also is there any advantage in using a ball hitch that extends 4-6 inches further away from the bumper than the standard length hitch where the ball is just a couple of inches away from the outer edge of the bumper?
Thanks for advice on a subject that is not in my past experiences.

The WDH will push the ball out from the TV, but not unnecessarily. We run an E2 after having used a chain-based WDH and separate sway bar. We would never go back. My wife hated hitching up the Pod before the switch, but she doesn't mind it now with the E2.

As Charlie suggested, I looked online at Jet for the Fastway weight equalizers. The 600 seemed a bit lightweight for the application, unless I am misinformed. I thought the gross vehicle weight of both the TV and pod were to be combined to determine which equalizer to purchase. My Tacoma is more than 5,000 pounds when loaded for camping, and my 2017 179 pod is more than 3,000 pounds when loaded for camping. Does that make the Fastway 800 a better match?
Also, is there an advantage of the square bars over the round bars? My Tacoma has a five-speed automatic trans, and I usually drive in fourth gear when towing.
In my original post, I asked about using an extended shaft to push the ball a few inches away from the truck bumper — just to gain a better turning radius for ease in backing the trailer. But if it decreases the towing capacity I will just have to accept the fact that I cannot open the tailgate fully while connected.
